| 中文摘要 | The temperature-dependent interplane resistivity rho(c)(T) was measured in the hole-doped iron arsenide superconductor (Ba1-xKx) Fe2As2 over a doping range from parent compound to optimal doping at T-c approximate to 38 K, 0 <= x <= 0.34. The measurements were undertaken on high-quality single crystals grown from FeAs flux. The coupled magnetic/structural transition at TSM leads to a clear accelerated decrease of rho(c) (T) on cooling in samples with T-c < 26 K (x < 0.25). This decrease in the hole-doped material is in notable contrast to the increase in rho(c) (T) in the electron-doped Ba(Fe1-xCox) Fe2As2 and isoelectron-substituted BaFe2(As1-xPx)(2). TSM decreases very sharply with doping, dropping from T-s = 71 K to zero on increase of Tc from approximately 25 to 27 K. rho(c) (T) becomes linear in T close to optimal doping. The broad crossover maximum in rho(c) (T), found in the parent BaFe2As2 at around T-max similar to 200 K, shifts to higher temperature similar to 250 K with doping of x = 0.34. The maximum shows clear correlation with the broad crossover feature found in the temperature-dependent in-plane resistivity rho(a)(T). The evolution with doping of T-max in (Ba1-xKx) Fe2As2 is in notable contrast with both the rapid suppression of T-max found in Ba(Fe1-xTx)(2)As-2 (T = Co,Rh,Ni,Pd) and its rapid increase in BaFe2(As1-xPx)(2). This observation suggests that pseudogap features are much stronger in hole-doped than in electron-doped iron-based superconductors, revealing significant electron-hole doping asymmetry similar to that in the cuprates. |
